Question

I am using the log4j2 version 2.11.1. I have the below pattern in log4j2.xml

"%d %-5r %-5p [%t] [%x] [%c] [%M] [%L] - %m%n".
I want to filter the logs on [%t]

I tried RegexFilter=".Coherence." and ThreadContextMapFilter. Filter is not working.



<Configuration xmlns="http://logging.apache.org/log4j/2.0/config" status="DEBUG">
   <Properties>
     <Property name="basePath">../Log4j2Example/logs</Property>
  </Properties>
   <Appenders>
     <!-- File Appender -->
     <File name="FILE" fileName="${basePath}/logfile.log" append="true" >
      <PatternLayout pattern="%d %-5r %-5p [%t] [%x] [%c] [%M] [%L] - %m%n" />
         <RegexFilter regex=".*Cohernce.*" useRawMsg="true" onMatch="DENY" onMismatch="ACCEPT"/>
     </File>
     <File name="STRINGFILE" fileName="${basePath}/logfileAA.log" append="true" >
        <PatternLayout pattern="%d %-5r %-5p [%t] [%x] [%c] [%M] [%L] - %m%n" />
      <RegexFilter regex=".*Cohernce.*" onMatch="ACCEPT" useRawMsg="true" onMismatch="DENY"/>
     </File>

任何包含一致性的行都应重定向到log4j2。Appenders“ STRINGFILE”和“ FILE” Appender不记录它。

您可以使用RoutingAppender的getThreadName和LogEvent方法执行所需的操作。

这是一个简单的Java类，用于生成一些日志记录：

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class SomeClass {

    private static final Logger log = LogManager.getLogger();   

    public static void main(String[] args){

        log.debug("This is some debug!");
        log.info("Here's some info!");
        log.error("Some error happened!");

        Thread t = new Thread(new Runnable(){

            @Override
            public void run() {

                log.info("Here's some info!");
                log.error("Some error happened!");
            }

        }, "foo.Cohernce.1234");
        t.start();
        try {
            t.join();
        } catch (InterruptedException e) {
            log.error(e);
        }
    }
}

这是log4j2.xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>

     <File name="FILE" fileName="logs/logfile.log" append="true" >
      <PatternLayout pattern="%d %-5r %-5p [%t] [%x] [%c] [%M] [%L] - %m%n" />
     </File>
     <File name="STRINGFILE" fileName="logs/logfileAA.log" append="true" >
        <PatternLayout pattern="%d %-5r %-5p [%t] [%x] [%c] [%M] [%L] - %m%n" />
     </File>

        <Routing name="Routing">
            <Routes>
                <Script name="RoutingInit" language="JavaScript"><![CDATA[
                  if (logEvent.getThreadName() != null && logEvent.getThreadName().contains("Cohernce")) {
                        "Cohernce";
                    }else{
                        "OTHER";
                    }]]>
                </Script>
                <Route ref="FILE" />
                <Route ref="STRINGFILE" key="Cohernce" />
            </Routes>
        </Routing>
    </Appenders>

    <Loggers>
        <Root level="debug">
            <AppenderRef ref="Routing" />
        </Root>
    </Loggers>
</Configuration>

这是写入logfile.log的输出

2019-06-15 01:30:00,705 645   DEBUG [main] [[]] [example.SomeClass] [main] [12] - This is some debug!
2019-06-15 01:30:00,815 755   INFO  [main] [[]] [example.SomeClass] [main] [13] - Here's some info!
2019-06-15 01:30:00,818 758   ERROR [main] [[]] [example.SomeClass] [main] [14] - Some error happened!

这是写入logfileAA.log的输出

2019-06-15 01:30:00,822 762   INFO  [foo.Cohernce.1234] [[]] [example.SomeClass] [run] [21] - Here's some info!
2019-06-15 01:30:00,832 772   ERROR [foo.Cohernce.1234] [[]] [example.SomeClass] [run] [22] - Some error happened!

按转换模式[％t]过滤日志
